ULV (Ultra Low Volume) Fogging is the perfect solution for closed in areas where normal cleaning and disinfecting chemicals do not reach. It involves the vaporising of a sanitizing or disinfecting liquid into a fine mist by pressure that is then suspended in the air , the vapour then settles onto surfaces which leaves all contact areas sanitized and disinfected. ULV, cold foggers are idea to use indoors, as there is no heat (Thermal Foggers) and therefore less fire risk.
